Abstract
The invention discloses a tectonic earthquake prediction experimental device and method based on impedance analysis. The tectonic earthquake prediction experimental device is composed of an earth crust pressure receiving assembly (101), an impedance analyzer (3), a computer (4), a solidified filler (30) and an open caisson (32). Due to the fact that the solidified filler (30), the earth crust pressure receiving assembly (101), the open caisson (32) and the rock layer (33) are completely solidified together, under the tectonic movement effect on earth crust, when the crustal stress reaches and exceeds the ultimate strength of the rock layer, the rock layer suddenly deforms and even cracks, the stress borne by rock changes, and six impedance sensors on the earth crust pressure receiving assembly (101) solidified with the rock can sense stress changes from the front direction, the rear direction, the left direction, the right direction, the upper direction and the lower direction respectively. By means of data processing, the change of the stress borne by the rock is found, and earthquake early warning is carried out in time.
Description
Technical field
The present invention relates to a kind of tectonic earthquake prognostic experiment device and method based on impedance analysis, particularly relate to tectonic earthquake electric powder prediction.
Background technology
Earthquake is divided into tectonic earthquake, volcanic earthquake, depression earthquake and Tectonic earthquake four kinds, wherein, tectonic earthquake refers under tectonic movement effect, when terrestrial stress meets and exceeds the strength degree of rock stratum, rock stratum will produce distortion suddenly, and even breaks, energy is discharged quickly, just cause the earth vibrations, this kind of earthquake is called as tectonic earthquake, takes up an area shake sum more than 90%.
Earthquake prediction is world-famous puzzle, the first, and the impenetrability of the earth.Going up to the sky as everybody knows, it is difficult easily to enter ground, and we are the lower change occurred over the ground, can only be inferred by the observation on earth's surface; The second, the complicacy of the pregnant rule of earthquake.By expert's years of researches, recognize gradually now earthquake preparation, generation, development process very complicated, at different geological structures environment, different time phases, the earthquake of different earthquake magnitude all demonstrates quite complicated pregnant rule process; 3rd, the small probability that earthquake occurs.Everybody may feel, the whole world has earthquake to occur every year, some still larger earthquake.But for an area, the repeated time that earthquake occurs is very long, decades, centuries, more than one thousand years, and carries out scientific research, has statistical sample.And the acquisition of this sample, all very difficult for the rest of one's life.Because tectonic earthquake prediction is as a worldwide sciences problems, the effective way of tectonic earthquake prediction all in the prediction of effort research tectonic earthquake, is explored in the whole world, but just present, no matter domestic still in the world, also predict an earthquake to very difficult entirely accurate.
Summary of the invention
The present invention is according to practical application request, devise a kind of tectonic earthquake prognostic experiment device and method based on impedance analysis, in selected seismic experiment district, subdrilling diameter is the open caisson (32) of 30 centimeters, the degree of depth that open caisson (32) arrives lithosphere (33) through topsoil (34) is 2.0 meters, then pour into open caisson (32) the consolidation filling material (30) that the degree of depth is 0.5 ~ 0.6 meter, then progressively accept with the earth's crust pressure of wire rope hanging the ground portion that open caisson (32) transferred to by assembly (101), the consolidation filling material (30) that the degree of depth is 2.0 ~ 2.5 meters is poured into again to open caisson (32), and carry additionally vibrating head consolidation filling material (30) is tamped, continue to pour into consolidation filling material (30) to earth's surface, after 28 days, consolidation filling material (30), earth's crust pressure accepts assembly (101), open caisson (32) is consolidated completely.The earth's crust is under tectonic movement effect, and when terrestrial stress meets and exceeds the strength degree of rock stratum, rock stratum will produce distortion suddenly, and even breaks; When suffered by rock, stress changes, the earth's crust pressure together with rock bonding accepts 6 impedance transducers on assembly (101), can distinguish the STRESS VARIATION of perception from front, rear, left and right and upper and lower 6 directions; By data processing, Timeliness coverage earthquake precursors.Research shows, this kind of experimental provision and method, may be used for tectonic earthquake prediction completely.
The technical scheme that the present invention solves the employing of its technical matters is:
A kind of tectonic earthquake prognostic experiment device based on impedance analysis is by earth's crust pressure receiving unit (101), electric impedance analyzer (3), computer (4), consolidation filling material (30), open caisson (32) forms, and described earth's crust pressure accepts assembly (101) by No. 1 impedance transducer (201), No. 2 impedance transducer (202), No. 3 impedance transducer (203), No. 4 impedance transducer (204), No. 5 impedance transducer (205), No. 6 impedance transducer (206), lower house (1), upper shell (2), O RunddichtringO (5), insulation filler (6), wire guide (7), rectangular slot 1 baseplane (9), rectangular slot 2 baseplane (12), rounded trough bottom plane 1 (15), rounded trough bottom plane 2 (18), rectangular slot 3 baseplane (21), rectangular slot 4 baseplane (24), suspension ring (27), snap ring (28), wire rope (29), threaded hole (31) forms, when stress changes suffered by rock, accepted 6 impedance transducers on assembly (101) by the earth's crust pressure together with rock bonding, respectively perception is from the STRESS VARIATION in front, rear, left and right and upper and lower 6 directions, by data processing, find the change of rock stress, carry out earthquake pre-warning in time.
The present invention is compared with background technology, and the beneficial effect had is:
Because tectonic earthquake prediction is as a worldwide sciences problems, the effective way of tectonic earthquake prediction all in the prediction of effort research tectonic earthquake, is explored in the whole world, but just present, no matter domestic still in the world, also predict an earthquake to very difficult entirely accurate.When terrestrial stress meets and exceeds the strength degree of rock stratum, rock stratum will produce distortion suddenly, and even breaks, and is discharged by energy quickly, just causes the earth vibrations.
